C# Redis实战(三)

三、程序配置

在C# Redis实战(二)中我们安装好了Redis的系统服务，此时Redis服务已经运行。

现在我们需要让我们的程序能正确读取到Redis服务地址等一系列的配置信息，首先，需要在Web.config文件中添加如下信息：

    <?xml version="1.0" encoding="utf-8"?>  
    <!--  
      有关如何配置 ASP.NET 应用程序的详细信息，请访问  
      http://go.microsoft.com/fwlink/?LinkId=169433  
      -->  
    <configuration>  
      <configSections>  
        <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->  
        <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=5.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />  
        <section name="RedisConfig" type="RedisDemo.RedisConfigInfo, RedisDemo"/>  
      </configSections>  
      <RedisConfig WriteServerList="127.0.0.1:6379" ReadServerList="127.0.0.1:6379" MaxWritePoolSize="60"  
            MaxReadPoolSize="60" AutoStart="true" LocalCacheTime="180" RecordeLog="false">  
      </RedisConfig>  
      <connectionStrings>  
        <add name="DefaultConnection" providerName="System.Data.SqlClient" connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog=aspnet-RedisDemo-20131125110945;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnet-RedisDemo-20131125110945.mdf" />  
      </connectionStrings>  
      
    </configuration>  

 有了以上信息还不够，还需要用C#代码来读取并且操作，获取Redis配置的程序如下：

    public static RedisConfigInfo GetConfig()  
           {  
               RedisConfigInfo section = (RedisConfigInfo)ConfigurationManager.GetSection("RedisConfig");  
               return section;  
           }  
      
           public static RedisConfigInfo GetConfig(string sectionName)  
           {  
               RedisConfigInfo section = (RedisConfigInfo)ConfigurationManager.GetSection("RedisConfig");  
               if (section == null)  
                   throw new ConfigurationErrorsException("Section " + sectionName + " is not found.");  
               return section;  
           }  

 Redis管理类代码：

    /// <summary>  
           /// redis配置文件信息  
           /// </summary>  
           private static RedisConfigInfo redisConfigInfo = RedisConfigInfo.GetConfig();  
      
           private static PooledRedisClientManager prcm;  
      
           /// <summary>  
           /// 静态构造方法，初始化链接池管理对象  
           /// </summary>  
           static RedisManager()  
           {  
               CreateManager();  
           }  
      
      
           /// <summary>  
           /// 创建链接池管理对象  
           /// </summary>  
           private static void CreateManager()  
           {  
               string[] writeServerList = SplitString(redisConfigInfo.WriteServerList, ",");  
               string[] readServerList = SplitString(redisConfigInfo.ReadServerList, ",");  
      
               prcm = new PooledRedisClientManager(readServerList, writeServerList,  
                                new RedisClientManagerConfig  
                                {  
                                    MaxWritePoolSize = redisConfigInfo.MaxWritePoolSize,  
                                    MaxReadPoolSize = redisConfigInfo.MaxReadPoolSize,  
                                    AutoStart = redisConfigInfo.AutoStart,  
                                });  
           }  
      
           private static string[] SplitString(string strSource, string split)  
           {  
               return strSource.Split(split.ToArray());  
           }  
      
           /// <summary>  
           /// 客户端缓存操作对象  
           /// </summary>  
           public static IRedisClient GetClient()  
           {  
               if (prcm == null)  
                   CreateManager();  
      
               return prcm.GetClient();  
           }
